Two or three different ways
1: There is a type of inverter called "in-line" This type of inverter has AC in and out as well as DC in/out. It can charge the batteries if you have shore power and contains all the needed switching.. That is what I use in fact.
Foot note: though more expensive.. TRUE SINE is the preferred inverter and though I always thought MSW were more efficient. turns out that is not so.
Next you have "Stand along" inverters. these have 12 volt IN and 120vac OUT
You an use a common AUTOMATIC TRANSFER SWITCH (a small one, say 30 amp) Feed SHORE power to the GENERATOR terminals. Inverter to the SHORE terminals (I know that sounds backwards but this means if shore power is present it will switch over).
Or you can use a manual transfer system. One is a "Transfer switch" you can get at an electrical supply, this is a 3 position On/Off/ON switch rated for 20-30 amps Mains/Off/Inverter.
Or when my 30 amp transfer failed I put in a special outler and MANULLY move a plug from MAINS to Inverter for one circuit... the one powering this laptop just now.
